[solved] Which object type is QObject::sender()?

[ricardo]

Hi mates!

When I receive a signal, I'd like to know in my SLOT if the sender is a QDockWidget, how can I test which kind of object is QObject::sender()?

There is a method called isA but I guess is obsolete because is not available on qt4.5

Any idea?
Thanks in advance.


EDIT:

BTW, Why doesn't work this:
QDockWidget* dock=(QDockWidget*) QObject::sender();
But this works perfectly:
QObject* sender = const_cast<QObject*>(QObject::sender());
QDockWidget* dock = static_cast<QDockWidget*>(sender);
